MauiXamlBluetoothLe builds on Mac but only runs for Android platform.

Guys: Update. I apologize, I have been working and reviewing so many code repos searching for a solution to solve my MAUI cross platform requirements that I got my wires crossed on which sample app I was commenting on. In my case, I had downloaded a very neat and tidy sample Application called MauiXamlBluetoothLE which show cases Plugin.BLE for Maui.

Below is my experience with trying to run the application on a Mac in iOS Simulator (and tethered too). Maybe you can provide some guiadance…maybe not. Maui is very new and I am looking at it as a replacement for our Aging Xamarin forms application which is completely dependenty on Cross-Platform BLE support.

Thanks.

Steps to reproduce

1. Install Visual Studio 2022 for Mac (17.3.7)

2. Clone THIS repo and open in VS.

3. Build and run on ios simulator

Expected behavior

The App should load and display the landing page in iOS Simulator (Works fine for Android Simulator and Real Android device)

Actual behavior

code blows up and throws exception. Main message is the following:

This functionality is not implemented in the portable version of this assembly. You should reference the NuGet package from your main application project in order to reference the platform-specific implementation.
